Information on permissions:
- SMS permission: to read your text messages, so you can automatically decrypt them.
- Contacts permission: to display the name of the sender of the SMS.
None of these information are registred on the phone/in the internal memory/on the internet.
The sender and receiver must have an identical random key file on their SD cards, this file should be generated and exchanged in person in advance of communication. Future versions may support additional less secure algorithms without this requirement.
OTP is unbreakable when used with a truly random key ("Communication Theory of Secrecy Systems", C. E. Shannon, 1949).
In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. For example, with a left shift of 3, D would be replaced by A, E would become B, and so on. The method is named after Julius Caesar, who used it in his private correspondence.
Enter a password/key and then enter your message - the app will then encode it as well-scrambled gibberish! Highly recommended for spies of all experience levels as well as for those who simply enjoy the allure of cryptography. It is simple, effective, and sure to confuse the bad guys.
This is my first app; I hope you like it. I'd feel great if you could give it a positive review ;). Constructive criticism appreciated as well!
Your favorite app developer,
